About 5 years ago a neighbor living close to the park, made a little patch a no-mow-zone. We take Prom photos there and many in the neighborhood do the same.
However, this year some plants grew very high (about 3m / 10 feet) and there weren't flowers for a long time... We all laughed about it and talked about 'Jack and the beanstalk'. Since a week there are some flowers, but compared to all the leaves and height the flowers are tiny. So we still laugh.
